The element, oxygen, is in group 16, period 2 of the periodic table. Thus its electron configuration is 1s2 2s2 2p4. Oxide's ionic state is O2-, so to get its electron configuration we just need to add two electrons to the old one. That yields 1s2 2s2 2p6.
The electron configuration of oxygen in the oxide ion (O2-) is 1s2 2s2 2p6 (equivalent to the configuration of a neon atom), as the oxide ion has gained two extra electrons compared to a neutral oxygen atom.
The -2 charge ion with the same electron configuration as krypton is the oxide ion (O2-). Krypton has the electron configuration 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p6. The oxide ion gains two electrons to achieve a full valence shell, resulting in an electron configuration of 1s2 2s2 2p6.
The given electron configuration corresponds to the ion with a charge of -2, which is the oxide ion (O^2-). This ion is formed by the element oxygen when it gains two electrons to achieve a stable electronic configuration.
The electron configuration for the Co2 ion is Ar 3d7.
The electron configuration of a V3 ion is Ar 3d2.
The electron configuration of oxygen in the oxide ion (O2-) is 1s2 2s2 2p6 (equivalent to the configuration of a neon atom), as the oxide ion has gained two extra electrons compared to a neutral oxygen atom.
Oxide ion (O²⁻) has the electron configuration of a noble gas neon (Ne), which is 1s² 2s² 2p⁶.

The -2 charge ion with the same electron configuration as krypton is the oxide ion (O2-). Krypton has the electron configuration 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p6. The oxide ion gains two electrons to achieve a full valence shell, resulting in an electron configuration of 1s2 2s2 2p6.
Neon, if you are talking about an oxygen ion.
The given electron configuration corresponds to the ion with a charge of -2, which is the oxide ion (O^2-). This ion is formed by the element oxygen when it gains two electrons to achieve a stable electronic configuration.
The electron configuration for the Co2 ion is Ar 3d7.
The electron configuration of a V3 ion is Ar 3d2.
The electron configuration of the Co2 ion is Ar 3d7.
The electron configuration of an Sc2 ion is Ar 3d1 4s0.
Oxide is a negative ion because it is formed when an oxygen atom gains two electrons, resulting in a charge of -2. This electron gain occurs to achieve a stable electron configuration, similar to that of noble gases. The extra electrons give the oxide ion its negative charge, making it an anion in chemical reactions.
